Convert TXT MARKDOWN to FB2

Markdown Documentation files, often stored with a TXT extension, are utilized for writing plain-text formatted documents that are easy to read and convert to HTML. Originating in 2004 by John Gruber and Aaron Swartz, Markdown's intent was to create a simple syntax for writing web-based documents. It is widely adopted in software development, documentation, and content management systems due to its readability and ease of use. These files facilitate collaborative work and version control, making them indispensable in modern IT workflows.

The FB2 file extension stands for FictionBook 2.0, a popular XML-based eBook format. Initially developed in Russia for easy parsing and conversion across different eBook readers, it preserves metadata and structure effectively. FB2 is mainly used for fictional literature, allowing detailed descriptions of text formatting, titles, and subtitles, which enhances the user reading experience. Its open-standard nature ensures broad compatibility and ease of modification, making it a preferred choice in digital publishing.
